Transclusion within nested element with jQuery Ste

Question

I'm attempting to integrate jQuery Steps (Wizard generator) in an Angular.js application with a nested Google Maps element from angular-google-maps (https://github.com/angular-ui/angular-google-maps).

However, I get this error: https://docs.angularjs.org/error/ngTransclude/orphan - "Illegal use of ngTransclude directive in the template! No parent directive that requires a transclusion found."

It looks like I have been using $compile during the Angular.js link phase, but the <div ng-transclude></div> is not being replaced in the nested element.

HTML:

<div ng-app='tr'>
  <div outer=1>
      XZY987
      <inner>ABC123</inner>
  </div>
</div>    

Javascript:

var ngApp = angular.module('tr', []);

ngApp.directive('outer', ['$compile', function($compile) {
    return {
        restrict: 'A',
        link: function (scope, ele) {
            ele.wrapInner('<div class="steps-wrapper">');
            var steps = ele.children('.steps-wrapper').steps();
            $compile(steps)(scope);
        }
    };
}]);
ngApp.directive('inner', function() {
    return {
        restrict: 'E',
        transclude: true,
        template: 'WWW <div ng-transclude></div> UUU'
    };

});

Here, the 'outer' element represents the jQuery Steps 'wrapped' custom directive and the 'inner' element is the Google Maps custom directive with a transclude and a template.

I've been scratching my head on this one most of today so I hope its an easy solution for someone else to point out for me!

Thanks in advance... Nigel

The problem is that the inneris getting compiled twice. You might solve the problem using the compile function instead of the link one:

    compile: function(ele){
        ele.wrapInner('<div class="steps-wrapper"></div>');
        var steps = ele.children('.steps-wrapper').steps();
    }

You could also comment the $compile(steps)(scope); link in the link function as far as you don't have any other code to be compiled inside the outer tag.
